Issue about displaying circle on an existing image

When I tried to illustrate the feature clusters in the image as the color circles. After I imported two libraries: I imported these two related libraries:

from PIL import Image
from PIL import ImageDraw

I used the code like the following:

draw = ImageDraw.Draw(img1)
draw.ellipse((x-10, y-10, x+10, y+10), fill=(255,0,0,0))

The error I get is as the following:

File "assi_6.python", line 85, in main
    draw = ImageDraw.Draw(img1)
  File "/Users/qdai/anaconda/envs/vision/lib/python2.7/site-packages/PIL/ImageDraw.py", line 284, in Draw
    return ImageDraw(im, mode)
  File "/Users/qdai/anaconda/envs/vision/lib/python2.7/site-packages/PIL/ImageDraw.py", line 59, in __init__
    im.load()
AttributeError: 'numpy.ndarray' object has no attribute ‘load’
Solution

  • Mentioning numpy.ndarray in the error message gives a hint that the object img1 is not an image as PIL needs it for its methods.

    Try to create/load img1 using PIL methods to avoid that error.
